Question 6 of 10
What is the most logical first step in solving the equation x2 +6x+9 - 10?
A Factor the left side of the equation
B. Subtract 10 from both sides of the equation
C. Take the square root of both sides of the equation
D. Subtract 9 from both sides of the equation
SUBMIT
Answer:
A.factor the left side of the equation
sorry but to tell u the answer, I need to know this
is there an equal sign between 9 and 10 or it's just a minus sign?
I mean if it is a minus sign the first thing to do to solve the equation is 9-10 which gives you -1. but if there is an equal sign the first step is to subtract 10 from both sides of the equation which means your answer will be option B.
In ΔWXY, the measure of ∠Y=90°, XW = 61, WY = 60, and YX = 11. What ratio represents the sine of ∠W?
Answer:
11/61
Step-by-step explanation:
from trigonometry ratio sin w= Opp/hyp
opp = 11
hyp =61
therefore sin w =11/61
What is the slope of the line?
3(y - 1) = 2x + 2
Rewrite the equation in slope- intercept form.
3(y-1) = 2x + 2
Use the distributive property
3y-3 = 2x + 2
Add 3 to both sides
3y = 2x + 5
Divide both sides by 3
Y = 2/3x + 5/3
Slope = 2/3

You are arranging 60 pictures on a poster board. the board can fit up to 4 rows of pictures and each row can have up to 20 pictures. you want each row to have the same numbers of pictures. how many different ways can you arrange the pictures?
Answer:
2 different ways
Step-by-step explanation:
You are looking at the factors of 60.
1×60 does not work, too many pictures in a row.
2×30 does not work, too many pictures in a row.
3×20 THIS WORKS!
4×15 THIS ALSO WORKS!
5×12 Nope, too many rows
6×10, no, too many rows
So there's just two ways to arrange the pictures.

Answer:
80°
Step-by-step explanation:
the triangles are symmetrical. therefore their angles will be equal.
interior angles of a triangle = 180°
180° - 30° - 70° = m<D
80° = m<D

Volume of 8 and the product of 5 and q increased by 6 yeilds
88
Answer:
It could be either of two ways:
8
x
+
10
or
8
(
x
+
10
)
Explanation:
The wording is a little unclear because this could be done in two ways:
8
x
+
10
or
8
(
x
+
10
)
The first one is "the product of 8 and a number, increased by 10"
The second is "the product of 8, and a number increased by 10"
The one you might write depends on how you say the statement!
In either case, when you read the phrase "a number" in algebra, you make this the variable - whatever letter you prefer (does not have to be
x
!)
Step-by-step explanation:
The verbal statement of the given algebraic expression gives us; 5(q + 6) = 88
How to write Algebraic expressions?
Now, we are told that the product of 5 and q increased by 6 yields 88. Thus, the expression gives us;
5(q + 6) = 88
Therefore we can conclude and say that the verbal statement of the algebraic expression gives us;
5(q + 6) = 88

Answer:
1. At Kohls Mrs. House would pay $45.00 because %25 = $15 so I just subtracted %.60.00-$15.00.
2.((Number × Percent/100)) + Number
((38 × 15/100)) + 38
5.7 + 38
= 43.7
3. I say that Mrs. House should go-to target. And just by $1.30.
At Kohls, the speaker would be at $45.00.
At target, the speaker would be at $43.70.

The points (2, 5) and (6,-3) fall on a particular line. What is its equation in slope-intercept form?
y = -2
x+ ?
Answer:
y = -2x + 9
Step-by-step explanation:
slope intercept form : y = mx + b
where m = slope and b = y intercept
first let's find the slope
slope formula :
[tex]m = ( \frac{y2 - y1}{x2 - x1} )[/tex]
where the x and y values are derived from the given points
here we are given (2,5) and (6,-3)
(x1,y1) = (2,5) so x1 = 2 and y1 = 5
(x2,y2) = (6,-3) so x2 = 6 and y2 = -3
we now plug these values into the formula
recall formula
[tex]m= ( \frac{y2 - y1}{x2 - x1} )[/tex]
plug in x1 = 2, y1 = 5, x2 = 6 and y2 = -3
m = (-3 - 5) / ( 6 - 2 )
m = (-8)/(4)
m = -2
the slope is -2
now to find the y intercept we plug in the slope and the x and y value of a given point into slope intercept form and solve for b
y = mx + b
given point : (2,5) x = 2 , y = 5, m = -2
5 = -2(2) + b
5 = -4 + b
9 = b
so the equation would be y = -2x + 9
Is it possible to have a polygon with an exterior angle of 14 degrees
Answer:
No, a polygon cannot have a decimal number of sides.
Explanation:
exterior angle of a polygon = 360 ÷ number of sidesusing the formula:
14 = 360 ÷ number of sides
1/number of sides = 14/360
number of sides = 360/14
number of sides = 25.71428571
Answer:
all polygons have exterior angles that totL to 360 degrees from triangles to 20-gons. so 360 divided by 14 is 25.71 sides which is not possible because what would .71 of a side look like....now this is assuming that you were referring to regular polygon with all sides the same. I suppose you could gave a polygon with a whole number of sides but the relationship between the exterior angles could be such that not all of the angles have the same degree measure. I would say that an exterior angle for any polygon would need to be greater than 0 but less than 360. so my answer is yes it could be possible le

y= -5x _
y=-7x-14
—————— (y-y=-5x-(-7x)-14)....
0=-2x-14 => x=-7 => y=-5*(-7)=35
Answer: x = -7 and y = 35
Step-by-step explanation: STEPS USING SUBSTITUTION
y= -5x
y= - 7x - 14
consider the first equation. Add 5x to both sides.
y + 5x = 0
consider the second equation. Add 7x to both sides
y + 7x = -14
to solve a pair of equations using substitution, first solves one of the equations for one of the variables then substitute the result for that variable in the other equation. and so goes on

What is the area of the base? ( 1 point) Explain or show your reasoning. (2 points)
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².
VolumeVolume is the amount of space occupied by a three dimensional shape or object.
Area of triangle = (1/2) * DF * height
Height = 10 - 6 = 4 mm, DF = AC = AB + BC = 2 + 3 = 5 mm
Area of triangle = (1/2) * 5 * 4 = 10 mm²
Volume of triangle prism = Area of triangle * AG = 10 * 4 = 40 mm³
Volume of rectangular prism = A to F * AC * AG = 6 * 5 * 4 = 120 mm³
Volume of crystals = 120 + 40 = 160 mm³
Area of base = AC * AG = 5 * 4 = 20 mm²
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².
